THE INGREDIENT LIBRARY
Retinoids.
The science of retinoids in skincare.
02
Formulation context
Consider the ingredient’s concentration, stability and delivery within the complete formula.
03
Reading the evidence
Look for evidence relevant to the specific ingredient and finished skincare product.
Good questions. Clear answers.
Why does the specific retinoid matter?
Retinoid is a family name rather than a single ingredient. Identifying the specific ingredient helps put formulation information and supporting evidence into context.
Why consider the complete formula?
An ingredient name alone does not describe the finished product. Concentration, stability, delivery and product-specific testing all provide useful context.
